Hello, i have a problem

with my script, i read a file csv with firstname, lastname, group

and i must check if group exist, if not i mus create it.

and then create user and give him group.

liste="liste_etudiants.csv"
cat $liste|
while read users;
do
l1prenom="$(echo $users | cut -c2 | tr -d '"')"
nom="$(echo $users | cut -d, -f2 | tr -d '"')"
group="$(echo $users | cut -d, -f3 | tr -d '"')"
echo "$group"
login="$l1prenom$nom"

pwd=$(head -c 500 /dev/urandom | tr -dc a-z0-9A-Z | head -c 10);

/usr/bin/id -g $group 2>/dev/null
if [ $? -eq 0 ]; then
echo "Le Groupe existe on va cree le user."
/usr/bin/id $login 2>/dev/null
if [ $? -eq 0 ]; then
echo "User trouve"
exit 1
else
#create user and apply group
useradd -md /home/ $login -g $group -p $pwd $login
fi
else
#create group
groupadd $group;
#creat user
echo "useradd -md /home/ $login -g $group -p $pwd $login"
fi

done

here is the back of the script when i apply it.

L1
is not a valid group name
-p AZSrMjZM94 pmartinrtin -g L1
L2
is not a valid group name
-p 9jsnLs8PyH felkouhenuhen -g L2
L1
is not a valid group name
-p w6Vw6LwNEa fgeorgesrges -g L1
L1
is not a valid group name
-p 95MVvcHstK stebibebib -g L1
L2
is not a valid group name
-p G4W0OjfPTg nduvallierlier -g L2
L2
is not a valid group name
-p qyDEhgCqBP smartinrtin -g L2
L2
is not a valid group name
-p WwrBZ4jF7g pmartinrtin -g L2

i don't understand why groupadd L2 is not ok.

Thanks for your answers

I think your file was created on a Windoze system, and each line ends
with a CR character, which your script tries to use as part of the group
name.
